ATTACHMENT TO WASI-IBASIN DRAIN-PIPES.

Application filed September 3, 1912.

To all whom it may concern Be it known that I, lVIL'roN Tnprnn, of the city of Winnipeg, in the l rovince of lllanitoba, Canada, have invented certain new and useful Improvements in Attachments to Vashbasin Drain-Pipes, of which the following is the specification.

The invention relates to a device attachable to the ordinary drain pipe of a wash basin and the object of the invention is to provide an inexpensive and efficient device which can be readily attached to the drain pipe and will operate to prevent the pipe from freezing up.

The device is particularly designed for use on railroad. cars where considerable difficulty is experienced in colder countries owing to the pipes freezing up due to the taps leaking. Drops of water trickle down the drain pipe and freeze at the lower end where the pipe opens to the exterior of the car. An icicle forms and accordingly enlarges until the pipe is completely closed. With my device attached the probability of this happening is reduced to a minimum.

It consists essentially in a small reservoir attached to and opening to the drain pipe and carrying a flushing valve, the reservoir being arranged to collect water and free it in quantities, the freed water being passed around the drain pipe, the parts being arranged and constructed as hereinafter more particularly described.

Figure 1 represents a vertical sectional view through the device showing it applied to a wash basin. Fig. 2 represents an en larged detailed horizontal sectional view through the reservoir, the section being taken in the plane denoted by the line YY Fig. 1. Fig. 3 is an enlarged detailed vertical sectional view through the seat.

In the drawing like characters of reference indicate corresponding parts in each figure.

1 represents a wash basin fitted with the usual taps 2 and 3 and plug 4 which closes the opening in the basin.

5 represents a casting providing a reservoir 6 having a cross plate or partition 7 therein fitted with a valve opening or passageway 8 the plate dividing the reservoir into two compartments a and b The casting is formed also with a single intake pipe 9 leading to the reservoir and two out let pipes 10 and 11 leading therefrom, the

one being contained within the other. The pipe 10 is in reality an extension of the pipe 9 and opens to that portion of the reservoir above the dividing plate while the pipe 11 opens to the reservoir beneath the dividing plate. The pipe 9 screws into the usual boss 12 formed on the water basin.

13 is a drain pipe connected directly with the pipe 10 which pipe passes beneath the car floor 1 and terminates about the same point as the present drain pipe. 15 is a second pipe receiving the pipe 13 and coupled up with the pipe 11. This pipe passes also through the car floor and terminates slightly above the lower end of the pipe 13.

The bottom of the reservoir 6 is closed by a screw plug 16 which carries a stufiing box 17, the stuffing box forming the bearing for the stem 18 of the valve 19. The valve is fitted with a rubber or other such like washer 20 which engages with a further rubber or such like washer 21 carried by the dividing plate 7.

22 is a lever pivotally secured at 23 to the side of the casting and having the lower end thereof slotted at 24 and receiving a pin 25 carried by the lower end of the valve stem. A weight 26 is adjustably secured to the upper end of the lever by a set screw 27. It is to be noticed that the lever is constructed so that very little downward motion on the part of the valve causes the weight to assume practically an upright position. The reason for this will bemore apparent later.

In order to understand the device more thoroughly I will now describe its operation assuming that the pipe 13 has become closed up through ice 28 forming on the lower end thereof. 7

When a party has finished using the wash basin he releases the water 29 therein by withdrawing the plug at in the usual way. This water flows down the pipe 9 to the pipe 13 where it backs up owing to the ice and overflows into the top of the reservoir. The valve is normally held shut by the weight. However as soon as the weight of the water overflowing into the reservoir becomes great enough to force the valve down the water in the reservoir will be free to escape to the pipe 10 and then directly to the pipe 15. This water which is more or less warm will operate to thaw out the pipe 13. It will be noticed that as soon as the valve is forced down the action of the weight becomes accordingly lessened through its being passed will have no tendency to close until all the water is passed out of the reservoir, in other words the initial tendency of the valve of itself to remain unseated with no water in the reservoir will just be vercome by tile tendency of the weight to swing from a point almost directly above the pivot pin 23 to its lower position. This feature of the attachment assures that the water will be expelled from the reservoir in sufficient quantities through the pipes 11 and 15 to have a thawing out effect on the pipe 28. In case the pipe is frozen up by the taps leaking and no one uses the basin the water leaking from the taps will trickle down the pipes 9 and 13 and gradually back up the pipes and overflow into the top portion of the reservoir. This will continue until the reservoir is filled to, a suificient height to set off the valve in the same manner as that previously described.

hat I claim as my invention is l. The combination with a wash basin, and a drain pipe passing from the same, of a divided reservoir having two compartments therein, one of said compartments opening to the drain pipe, a pipe receiving the drain pipe and opening to the other of the compartments and means for controlling the fiow of a liquid from one compartment to another, as and for the purpose specified.
